(o1. 221-100) g p p v a g This invention relates to hose nozzles; and it at serves to render the juncture between the has reference more particularly'to nozzles for the elbow 12 andthe-fitting 14 fluid tight. The disdrain hoses of vehicles used in delivering gasoline charge end of the elbow 12 :it will be noted, is

oils and other liquid'commodities. somewhat enlarged diametrically as atv 16 and When unloading gasoline, for example, from formed with an internal screw thread 17 of 'rela-' the delivery vehicle, a nozzle is attached torthe tively coarse pitch. This thread 17 extends up'to end of the drain hose and inserted into the inlet ,a shoulder 18 beyond which there is an annular pipe of the underground tank at'thegas filling or channel 19, which with said shoulder jointly form service station where delivery is being'made. In a retaining groove to receive the circumferential order that unloading maybe accomplished in a fiangeof a C rcu a as of rectangular minimum of time, it is requisite that the bore of -L-shaped rosss cti n, whe th opening rthe nozzle tip be equal to that of the drain hose, responds in diameter to that of the flow passage and this is the type of nozzle which it is therefore '21 through the elbow l2 a d makes a flush surface most advantageous to use.v However, in a great her with w mpr ss d as Shown in 5---many service stations, the tanks are fitted with it being read y understood that the boreof said small inlets which vary in diameter and which ask t i ini ially sli ht y r ter han that of will not receive the large nozzle tip on the drain the 110w Pa 21, While the portion thereof hose. In such instances, the nozzle is ordinarily agingth should r 18 x n o w y therebushed down by means of pipe reducers and a tip beyond, v indicated at to r Such go of smaller diameter is applied to uit the inlet pr ssi n I p a ti th as t 0 is made from of the particular tank which is to be charged a relatively soft resilient material which yields The making of such changes is time consuming, readily to compression and which is resistive to troublesome due to difficulty in securing fluid tight erosion y gasoline O I I joints, and moreover entails the use of wrenches interchangeable use With the y mb and other tools. As a consequence, the truck or elbow 12 of the nozzle 11, I have provided a drivers will invariably use only the smallest size number of nozzle p three being S Wn for tip because it can be universally employed, since convenience of illustration, the same being respecthe timelost in unloading under these conditions tively designated by h reference Characters is probably nomore than that required to make 220 a 22b in Figs- II x p for 3 -nozzle substitutions as aforesaid. having tu u a prolohgatiohs 23a n 3 of Myinvention is. directed in the main t ward different diameters and for a slight modification overcoming the several drawbacks which have hereinafter referred-to, the tips 23a and 23b are been mentioned, through,v provision of a, nozzle Of the same construction as .the tip 23 so that with interchangeable tips of different sizes cathe descript on of the latter Will, in general, d 35 pable of being quickly and easily attached and for them all. Referring again'to Fig. I it will be detached byhand without necessitating the aid of observed that the prolongation 23 of the tip 22 is I wrenches or other tools forthe purpose. formed from tubing preferably of high strength Other objects and attendant advantages of this alloy bronze, thev upper end of the tube being set invention will be manifest from the following deintoa collar 24 which has a coarse pitch external 6: tailed description of the accompanying drawing, screw thread 25 to fit the'thread 17 in the elbow wherein, Fig. I is a fragmentary view partly in discharge enlargement 16. In order to secure the elevation and partly in section showing my imtube 23 permanently to the collar 24 it is cirproved hose nozzle. 7 p g cumferentially expanded as at 26 into an internal Figs. II and III show different interchangegroove of said collar; and after assembling of the able tips for the nozzle. partsin this manner, the tube 23is soldered or 7100;

, With reference first to Fig. I of theserillustrawelded to the'collar 24 aroundthe bottom edge tions, the numeral 10 designates a flexible drain of the latter as at 27. The tip of Fig. I has a bore hose such as is used inconnection with gasoline 28 corresponding exactly to that of the passage or oil delivery vehicles; while 11 indicates the 21 through the elbow 12.

5 nozzlewith which the present invention is more i The substitutable nozzle tips 22a and 22b on especially concerned. 'As shown, the nozzle 11 the other handhave bores 28a and 28b smaller comprises a hollow body member having, in this than those of the tip 22, and in order to promote instance, the form of an elbow 12 which screws smooth fluid flow through them, mergent roundonto the threaded nipple 13 of a terminal fitting ings are formed interiorly of the collars 24a and 55 "14 at the end of the hose 10. A washer indicated 24b as at 29a, 29b to render the bores of said tubes 7 I complished in a minimum of time. In attaching the tips 22, 22a and 22b, their collars 24, 24a. and 241) are screwed into the elbow 12 until their top ends engage the shoulder 18 within said 'elbo'w. The shoulder 18 thus acts, as a. stop. to limit the extent to which the gasket 20 may be compressed.

and thus prevents undue distortion such as would tend to dislodge said gasket from its retaining groove. Due to the softness of the gasket 20,- the screwing up of the tips 22, 22a and 22b, may be effected by hand with assurance of a fluid tight juncture between the. parts. Accordingly no tools are required in changing my improved nozzle 11 to suit all conditions imposed in practice.

Having thus described my invention, I claim: 1. A hose nozzle comprising an'elbow-havingone end adapted for coupling connection to the hosev and its other end enlarged and provided with an internal coarse-pitched screw-thread extending up to a shoulder therein beyond which is formed an annular channel. said shoulder and channel jointly defining a retaining groove of rectangular cross-section, a similarly-sectioned annular gasket seated in said retaining groove andhaving a' bore. slightly greater thanthat of the flowpassage through the elbow with that portion thereof engaging the shoulder aforesaid projecting outwardly therebeyond, and a tip formed of thin tubing with an attaching collar at one end externally screw-threaded to fit into the elbow discharge end as far asv permitted by the shoulder therein with incidental limited compression of the annular gasket to provide a fluid-tight seal and safeguarding said gasket against dislodgment from the retaining groove. 7

2. .Tlhe combination of claim 1 wherein the tip tubing is'circumferentially expanded into an internal groove. ,of the attaching collar and said parts are permanently united together.

3. The combination of claim 1 wherein the bore of the attaching collar ismergently rounded to accommodate tubing of smaller bore.
